Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
According to an aspect of the present utility model; the utility model provides a kind of cushion for Ballast track sleeper; this cushion is used for being arranged between sleeper and railway roadbed to provide resiliency supported to sleeper; cushion comprises superposed elastic layer 1 and supports the topping 2 of elastic layer 1 in bottom regularly; elastic layer 1 can the bottom of support sleeper, and topping 2 is made up of high-abrasive material and between elastic layer 1 and railway roadbed.As shown in Figure 1 to Figure 3; cushion comprises elastic layer 1 and topping 2; elastic layer 1 can be arranged on the bottom of sleeper and provide resiliency supported for sleeper; topping 2 is made up of high-abrasive material; this topping 2 is fixedly fastened on the bottom of elastic layer 1; and between elastic layer 1 and railway roadbed, thus not only have and can prevent elastic layer 1 from sustaining damage and improving the effect in the application life of elastic layer 1, but also there is the effect of the stability that can improve track structure.
Preferably, the surface towards railway roadbed of topping 2 is formed with anti-skid structure.Namely; topping 2 on the surface of elastic layer 1, be formed with anti-skid structure; can appropriate configuration be formed as this anti-skid structure, as long as the frictional force that the surface that can increase topping 2 contacts with railway roadbed, thus there is the effect of the stability improving track structure.
Preferably, anti-skid structure is formed as multiple protuberance 3, is arranged on the described surface of topping 2 multiple protuberance 3 predetermined space.As shown in Figures 2 and 3, the shape of described protuberance 3 can be rectangle, can be also irregular shape, be not particularly limited this.By by multiple protuberance 3 predetermined space be arranged in topping 2 towards on the surface of railway roadbed, thus the frictional force between topping 2 and railway roadbed can be improved equably.
Preferably; the projecting surface 4 of protuberance 3 is in the same plane; thus projecting surface 4 and the railway roadbed uniform contact of each protuberance 3 on the surface of topping 2 can be ensured; frictional force between the projecting surface 4 of the protuberance 3 of topping 2 and railway roadbed is kept evenly, thus can the concentrated wear of effective protection aquiclude 2.
Preferably, as shown in Figure 3, protuberance 3 is formed as extending along the longitudinal direction A on described surface on the described surface of topping 2, or, preferably, protuberance 3 is formed as along vertically extending with the longitudinal direction A on described surface on the described surface of topping 2, but the utility model is not limited thereto, as long as the effect of the frictional force between the surface towards railway roadbed and railway roadbed improving topping 2 can be played, described protuberance 3 also can be formed as other structures, such as, described protuberance 3 comprises the first protuberance and the second protuberance, first protuberance extends along the longitudinal direction A on the described surface of topping 2, second protuberance is along vertically extending with the longitudinal direction A on the described surface of topping 2, thus the frictional force improved between protuberance 3 and railway roadbed.
Preferably, topping 2 is made up of ethylene propylene diene rubber or polyurethane, and containing macromolecular fibre in topping 2.Preferably, described macromolecular fibre is polyester fiber.By admixture macromolecular fibre composition in topping 2, improve the puncture-resistant of topping 2, cracking resistance and anti-permeability performance, thus effectively can reduce topping 2 and be damaged, and then improve the application life of cushion.At this, described macromolecular fibre can be also other fibers, as long as can improve the anti-wear performance of topping 2.
In addition, preferably, elastic layer 1 is made up of expanded material thus can effectively for sleeper is provided resiliency supported, and wherein, this elastic layer 1 can be made up of ethylene propylene diene rubber or polyurethane.But the utility model is not limited thereto, elastic layer 1 also can adopt other materials, as long as can provide elasticity for sleeper.
In addition, according to another aspect of the present utility model, the utility model also provides a kind of Ballast track; this Ballast track comprises cushion as above; this cushion is arranged between sleeper and railway roadbed, and elastic layer 1 contacts with the bottom of sleeper, and topping 2 contacts with railway roadbed.
Wherein, because topping 2 is arranged on the bottom of elastic layer 1 by high-abrasive material and is contacted with railway roadbed; thus can play protection elastic layer 1 be not damaged; make elastic layer 1 can effectively for sleeper provides resiliency supported; in addition; the frictional force that can improve between topping 2 and railway roadbed because topping 2 has anti-skid structure, thus the effect with the stability improving track structure.In addition, owing to containing macromolecular fibre composition in topping 2, thus puncture-resistant, cracking resistance, the anti-permeability performance of topping 2 can be improved, and then improve the application life of cushion.Cushion of the present utility model not only can be applied to the sleeper of the Ballast track in common railway, high-speed railway, subway and light rail, but also can meet the instructions for use of the sleeper of heavy haul railway Ballast track.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the utility model illustrates no longer separately to various possible combination.
